Radio model updating


The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.

CLAIM OF PRIORITY UNDER 35 U.S.C. §119 and §120

This application is a continuation of U.S. patent application Ser. No. 13/078,644, filed Apr. 1, 2011, and entitled “Radio Model Updating,” which claims priority under 35 U.S.C. §119 to U.S. Provisional Application Ser. No. 61/320,966, filed 5 Apr. 2010, and entitled “Indoor Navigation with Server Interactions,” which are assigned to the assignee hereof and which are incorporated herein by reference.

BACKGROUND

1. Field

The subject matter disclosed herein relates to radio model updating.

2. Information

Humanity has continually struggled to journey from one point to another. In ancient times, individuals in unfamiliar territory wandered around without guidance, or perhaps they risked asking local inhabitants for directions. People eventually developed maps to provide written guidance for reaching a desired destination. As literacy and the availability of paper became more common, more people gained the ability to use maps during their travels.

Maps began to be available in electronic form during the twentieth century. With the advent of the Internet, people could electronically access maps of many places from all over the globe. Web mapping services could also provide directions from point “A” to point “B”. These directions from web-based mapping services were relatively static. With the invention of satellite-positioning system (SPS) technology and ever-smaller electronic devices, however, so-called turn-by-turn directions could be provided dynamically as travelers journeyed toward their destination.

These electronic maps and web-based mapping services focus on providing directions in particular environments and certain situations. Unfortunately, there are other environments and situations for which they have not been designed. Consequently, there remain a number of areas in which navigational or other location-based services may be improved.

BRIEF DESCRIPTION OF THE FIGURES

Non-limiting and non-exhaustive aspects, features, etc. will be described with reference to the following figures, wherein like reference numerals may refer to like parts throughout the various figures.

FIG. 1 is a schematic block diagram illustrating a mobile device within an example indoor environment in which the mobile device may be provided access to indoor environment characteristics via one or more server devices such that a location-based service may be provided according to an implementation.

FIG. 2 is a schematic diagram of an example indoor environment, within which a mobile device may navigate, that may include multiple obstacles or a multitude of feasible positions for mobile devices according to an implementation.

FIG. 3 is a schematic block diagram illustrating example interactions among a mobile device and one or more server devices, which may include a crowdsourcing server device, according to an implementation.

FIG. 4 is a block diagram of example indoor environment characteristics, which may include a radio model, according to an implementation.

FIG. 5 is a schematic block diagram illustrating example interactions among multiple mobile devices and at least a crowdsourcing server device to provide an updated radio model according to an implementation.

FIG. 6 is a flow diagram illustrating an example method for one or more server devices to update a radio model according to an implementation.

FIG. 7 is a flow diagram illustrating an example method for a mobile device to use an updated radio model according to an implementation.

FIG. 8 is a flow diagram illustrating an example method for a mobile device to participate in updating a radio model according to an implementation.

FIG. 9 is a schematic diagram of at least a portion of an indoor environment in which mobile devices may experience examples of incidents that apparently conflict with a graph, and at least one of these incidents may result in a graph updating operation.

FIG. 10A is a flow diagram illustrating an example method for a mobile device to participate in updating a graph according to an implementation.

FIG. 10B is a flow diagram illustrating an example method for a mobile device to use an updated graph according to an implementation.

FIG. 11 is a flow diagram illustrating an example method for one or more server devices to update a graph according to an implementation.
